  • How would you describe Newton's first law using this picture?
    The ball will only move if you kick it. Once it's moving, it will keep on moving until the net stops it (acteed upon by another force.)
  • Where is the rudder located?
    On the vertical stabilizer, on the back of the tail/fin.
  • In Newton's equation F = m * a, what does the m stand for?
    mass
  • How does the shape of a plane's wing affect its ability to generate lift?
    air travels faster over the longer/curved surface on top. This creates a low pressure "vacuum." There is a high pressure created under the wing.
  • Which of Newton's law would explain how the pogo stick allows its user to jump up and down.
    3rd: Equal and opposite reaction. The spring compresses and then spring open.
  • What force is opposite thrust?
    drag
  • What does Newton's First Law say about inertia?
    An object at rest will stay at rest unless acted upon by another force.
  • What is the force of gravity that is pulling down on a plane while it's in flight?
    Weight
  • Where are the plane's elevators located?
    Horizontal stabilizers, mounted on the tail/fin or the plane
  • What does yaw mean? Show the type of motion it represents.
    It's a turn, pivoting along a vertical axis.
  • The hockey puck will slide along the ice, but not unless the hockey player hits it with his stick. Which of Newton's laws is this?
    1st: Inertia. The puck will move only if acted upon by another force.
  • In Newton's equation F = m * a, what does the F stand for?
    Force
  • What part of the plane controls the plane's pitch?
    elevators
  • Describe how the ailerons' movement allows the plane to roll.
    They rotate opposite each other. Whichever aileron is rotated upwards has less lift and less drag. That causes you to turn in that direction.
  • What is the upward force that allows a plane to raise off the ground and stay in the air?
    Lift
  • Explaiin how a rocket launching from earth demonstrates Newton's 3rd Law.
    The rocket is pushing away from the explosion (caused by the fuel). The explosion is pushing away from the rocket.
  • Which principle of flight is this?
    Lift
  • How does hitting a baseball off a batting tee demonstrate Newton's 1st law?
    An object at rest--the baseball--will stay at rest--on the tee--until a force--the bat--hits it.
  • Newton says that two factors affect acceleration. What are they?
    1. The mass of an object 2. The size of a force acting on the mass
  • What is the benefit of using a prototype when working on a project?
    It allows you target areas that need improvement and make minor changes alone the way. It saves money and time.
  • Where do you find the plane's ailerons?
    on each wing
  • What do you call the force of resistance that is working against thrust?
    drag
  • Which principal of flight is this?
    Thrust
  • How does Newton's cradle explain his third law?
    For every action, there is an equal and opposite reaction. One ball will cause one ball on the other end to move. Two balls will cause two balls to move. Etc.
  • How would you describe Newton's second law using this picture?
    A greater force is required to move a larger mass.
  • In Newton's equation F = m * a, what does the a stand for?
    acceleration
  • What is the shape of a plane's wing?
    airfoil
  • How would you describe THRUST (with regard to a plane in flight)?
    It is the forward motion.
  • A wheelbarrel full of rocks is harder to move than an empty one because there is more mass. Explain how this relates to Newton's 2nd law.
    It takes more force to move a greater mass.
  • What is the equation in Newton's second law:
    F = m * a (Force equals mass times acceleration)
  • What is is called when the nose of the plane is pointing up or down?
    pitch
  • Which principle of flight is this?
    Weight
  • What is the science word that means something at rest will stay at rest. (Think Newton's 1st law)
    Inertia
  • Which principle of flight is this?
    Drag
  • What force is opposite drag?
    thrust
  • What part of the plane controls the yaw?
    rudder
  • What force is opposite lift?
    weight
  • What is the principle of flight that is controlled by the engine(s) or propeller(s)?
    thrust
  • What force is opposite weight?
    lift
  • What part of the airplane allows the plane to roll?
    ailerons
